For sale by the Superintendent of Documents, U. S. Government Printing Office Washington 25, D. C. - Price $2 [Illustration: (Map of Korea, indicating battle fronts in July, 1950.)] [Illustration: THE PUSAN PERIMETER AUG.-SEP. 1950 GENERAL DISPOSITION OF 8TH ARMY & NORTH KOREAN FORCES] Transcriber’s Notes Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in the original book; otherwise they were not changed. Simple typographical errors were corrected; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced. The index was not checked for proper alphabetization or correct page references. When illustrations had no captions or useful headings that could be used as captions, Transcriber added them and placed them in parentheses, usually by copying them from the List of Illustrations on page ix. Those parenthetical captions will be visible only in versions of this eBook that do not display the actual illustrations. The first two maps are identical to the last two maps. Footnote 265, originally footnote 7 on page 148: “18 May 5” was printed that way, with an incomplete year. Footnote 278, originally footnote 6 on page 176: “Plan 13-60” was printed that way. All other Plans are numbered as “nn-50”, so this may be a misprint. Page 245: Transcriber added “BuAer” and “LSD” to the Glossary. Page 266: “Ground,” an index entry following “Marine Helicopter Squadron (Experimental)” under “Marines,” did not include a page reference.
